I know you can assess your own opinion from other posts, but is there anyone out there that can honestly tell me if the NGK R7437-8 plugs that are in my car now and the Denso IKH24's are equivilant? I am curious because I am due for new plugs in a bit and would rather pay the $12 per plug vs. $40 for the NGK"s, but am willing to pay the $40 if there is a difference. Otherwise its just preference right? Denso? NGK's? I mean, hell they both are very good if not the best out there reliability wise. Your thoughts please.....

and they want how much for a new MR? Damn!!! haha

 

I know the IKH24 are one-step colder than the stockers but I'm not sure if the NGK R7437-8 are the same.

Buy the Denso ones, you'll be fine with those.
